MACHINE FOR APPLYING RIBBED STRIPS ON INSOLES May 24, 1960 5Sheets-Sheet 5 Filed Dec. 5, 1956 A I I United States Patent 10 MACHINEFOR APPLYING RIBBED STRIPS N INSOLES- Gerhard Gertz, Alfeld, Leine,Germany, assignol' to Schuhmaschinen-Gesells'chaftj Hanke: & Co. m.b.H.,Alfeld, Leine, Germany The present, invention relates to newimprovements in shoemaking, machinery and more. particularly to amachine for cementing a ribbed sewing or reinforcing strip upon aplaneinsole or for gluing a reinforcing strip upon an insole which. hasbeen provided with. arib which is formed by splitting the insoleat the.inside or the outside or at both sides thereof.

It is an object of the present invention to provide a single machinewhich permits both. functions tobe carried out, namely, to apply aribbed strip upon, a plane insole, as well as to apply a reinforcingstrip to a split insole and the rib thereon which is formedby the splitportions.

The machines which. were known. for. this purpose priorto this inventionoperate either with tong. arms which are movable relative to each other.or with rotating rollers. Other machines known for this purpose haverollers which merely serve for guiding a ribbed strip supplied thereto,while the two lateral Web portions thereof are pressed upon the planeinsole by means of a mechanism consisting of a hammer and an anvil.Those machines which operate with tong arms. have the disadvantage thatthe insole with the reinforcing or ribbed. strip cemented thereon isadvanced in a step-bystep movement rather than continuously as Withpressure rollers. Such machines operating with tongs also do not permitthe reinforcing or ribbed strip to move around an arc of a relativelysmall radius. This. disadvantage is avoided in machines operating with.pressure rollers, provided these rollersacting upon the ribbed orreinforcing strip are disposed so that their rotary axes extend parallelto each other. However, such machines operating with pressure rollers aswere known prior to this invention could only be used either forapplying reinforcing strips uponv insoles on. which; the rib. was formedby splitting the insole or. for cementingprefabricated ribbed stripsupon the insoles. Therefore, it was previously impossible touse only.one; machine to. carry out both of these functions.

For attaining the above-mentioned object of. the invention, namely, toprovide a machine: which. permits both functions to be carried out onthesame machine, the invention first provides a. mechanism. for cementing areinforcing strip upon an. insole whichds... split on. the inside oroutside or on both sidesthereofsoas-to form a rib consisting of twolips. This..mechanism.consists of two rotating pressure and feedmembers. which are applied at the same side of the insole, and areciprocating pressure member forv pressing the reinforcing strip uponthe surfaces of the rib on the insole, and also for pressing the lateralwebs of such strip upon the surfaces of the insole itself. Althoughasimilarmechanism is known for gluing a prefabricated reinforcing stripupon an insole it does not permit any pressure to be exerted upon a ribon the strip in a direction substantially. per.- pendicular to thesurface. of the insole. Such pressure is also not required in the-knownmachines: since the prefabricated ribbed strip to be applied is flat anddoes not' contain or partly enclose a relatively rigid rib.

Another feature of the invention consists in, arrange ing the tworotating pressure and feed members at the sameside of the insole so thattheir rotary axes are dis-- posed perpendicularly to each other, and todesign and mount the reciprocating pressure member which, is movable ina straight direction so as to be disposed opposite to the pressure andfeed member which engages'into the space enclosed by the rib so thatthis reciprocating member will press the web portion on the inner side'of the rib against the insole.

Another feature of the invention consists'in providing the drive shaftof the rotating, pressure and feed member: which is disposed outside ofthe space enclosed by the rib in. the form of a hollow shaft, and tomount within said shaft the shaft of a third pressure or pressure andfeed member so that the latter projects beyond the other member. Theactive diameter of this third member: ismade smaller. than that of thesurrounding pressure and feed member, and it may be either freelyrotatable therein or also be driven. In the latter case it may servenot: only as a pressure member but also as a feed' member, and. the twotelescoped pressure and feed members; should then be driven; so as tohave the same peripheral speed, preferably by the same driving shaft bymeans of'bevel gears or the like. These two concentrical'members arepreferably also mounted so as to. be either slidable in. their axialdirection or to be pivotable', or to be movable in. both directions topermit them to be adjusted to various thicknesses. of; the splitportion. or the. rib formed thereby. Furthermore, in order to facilitatethe design and operation of the machine, the shafts of the pressure and:feed=members which are disposed vertically to each. other'may beinterconnected by. an endless. belt, for example, a chain, and may bothbe driven: by the. same main drlive shaft which also operatesthereciprocating. pressure member. The reciprocatory movement of thispressure member is: preferably attained by means of an. eccentric whichconnects the pressure member at? least indirectly with the main driveshaft'.

Referring 'tothe drawings, the macliinwffam'e 1 sup:

ports a main drive shaft 3 which is rotatably mounted thereon, forexample, by means of a bearing 2, and carries a worm 4 which is inengagement with a worm gear 5 secured to a shaft 6. This shaft 6 hasfurther secured thereon a gear 7 and a pinion 8. Gear 7 engages with agear 10 which is freely rotatable on a shaft 9 and secured to a sprocketwheel 11 which is likewise freely rotatable on shaft 9, while pinion 8engages with a gear 12 secured to shaft 9. The lower end of shaft 9carries suitable driving means, for example, a sprocket wheel 13, whichis connected by an endless power transmitting member, for example, achain 14, with a driven wheel, for example, a chain wheel 15 which issecured to a shaft 16. The upper end of shaft 16 carries a table 17which is rotatably mounted on a stationary column 18 by means of athrust bearing 19.

The power transmitting sprocket wheel 11 is connected by a chain 20 to asprocket wheel 21 and also to a sprocket wheel 22 so as to drive thesame. Sprocket wheel 21 is mounted on the upper end of a shaft 23, thelower end of which carries a bevel gear 24 which engages with anotherbevel gear 25 secured to a hollow shaft 26. This shaft 26 carries on itsother end a suitable pressure and feed member, for example, in the formof a knurled wheel 27 integral with shaft 26. The outer end surface ofwheel 27 is slightly conical, and may be more or less inclined relativeto the axis of shaft 26, for example, at an angle of 82, depending uponthe shape of the rib or ribbed strip to be applied to the insole. At itslower end, shaft 23 carries a further bevel gear 28 in mesh with a bevelgear 29 which is mounted on a shaft 30, the outer end of which carries afurther pressure member or pressure and feed member 31. Shaft 30 andmember 31 do not need to be driven, and in such event member 31 onlyacts as a pressure member upon the rib on the insole or of theprefabricated ribbed strip.

Sprocket wheel 22 is mounted on the upper end of a vertical shaft 32,the lower end of which carries a third pressure and feed member 33'whichmay, for example, be keyed thereon. One end of the main shaft 3 carriesan eccentric 34 having an arm 35 which reciprocates a connecting rod 37mounted on a shaft 36 which is slidable within the machine frame 1 so asto move upwardly and downwardly in the direction of the arrow 38, asshown in Fig. 1. The lower end of co'nnecting rod 37 carries a fourthpressure member 39 which, by the reciprocating movement of rod 37,hammers upon the inner web of a reinforcing strip or of the ribbed stripto apply the same to the surface 40 of insole 41. The pressure member 39is secured to connecting red 37, for example, by a screw 42. By turninga screw 43 which acts upon a stop member 44 it is possible to adjust thebearing members 45 and 46 together with all the parts mounted thereon bypivotal movement about the axis 47 in the direction of arrow 48, asillustrated in Fig. 4. Suitable means, not shown, may also be providedto prevent chain 20 from loosening when members 45 and 46 are beingpivoted. In place of the table 17, it is also possible to provide acounterroller 49, as shown in Fig. 5, which may be mounted on a shaft 50and be driven by shaft 9, for example, by bevel gears, not shown.

Figs. 6 and 7 show enlarged views of the essential parts of the machineaccording to Figs. 1 to 4 or 1 to 5, respectively, for illustrating thatthe same may be used either for applying a reinforcing strip on aninsole with a rib separate from the insole or with a rib formed bysplitting the insole. According to Fig. 6, the insole 41 is providedwith a ribbed strip consisting of an upstanding rib 51 and a reinforcingstrip 52. This ribbed strip is preferably prefabricated, the strip 52then being glued fully to the outer and upper surfaces of rib 51 andonly partly to the inner surface thereof before the entire ribbed stripis fed to the machine. Since the surface of rib 51 facing toward thesurface of the insole has a fishtail-like shape and the inner web of thereinforcing strip 52 is fed so as to lie at the higher level than thesurface of the insole to which it is to be glued, and since the pressuremember 39 exerts a pressure upon the inner web of the reinforcing stripin a direction perpendicular to the insole surface, the rib also isstrongly pressed against the insole surface and the rib and the webs ofthe reinforcing strip will be securely glued to each other as well as tothe upper surface of the insole. While the ribbed strip is beingapplied, the pressure and feed member 27 presses the outer Web of thestrip 52 against the insole and operates at the same time as a back restto to resist the pressure exerted by the pressure and feed member 33.The pressure or pressure and feed member 31 acts upon the upper edge ofrib 51 and assists and supports the attachment of the entire ribbedstrip to the insole caused by the downward drawing action of thepressure member 39 upon the inner web of strip 52. Fo'r compensating thedifference between the rotary speed of the knurled outer surfaces of thepressure and feed members 27 and 31, shaft 30 may be provided with anannular disk 53 which it fitted into member 27. This disk 53 does nothave to be secured to shaft 30 but may be freely rotatable thereon.

If the machine as previously described is to be used for applying areinforcing strip 56, as shown in Fig. 7, upon an insole 54 which haspreviously been provided with a rib 55 consisting of a pair of lipsproduced by an inner and an outer cut in the upper surface of theinsole, it will be necessary to exchange the pressure and feed member 27which acts upon the outer web of the strip, as shown, for example, inFig. 6, for a pressure and feed member 27 which is shaped in conformitywith the outer cut and adapted to engage in the recess in the insoleformed thereby. Also, the pressure member 39 as shown in Fig. 6 mustthen be exchanged for a pressure member 39 as shown in Fig. 7 to engagein the recess in the insole at the inner side of rib 55.

Fig. 8 shows a separate perspective view of the pressure member 39 whichis adapted to reciprocate in a straight line upwardly and downwardly.Its upper portion surrounds the drive shaft 32 of the knurled pressureand feed member 33, and its lower end is provided with a recess 57 whichpermits member 33 to pass into member 39 and operate freely therein uponthe reinforcing or ribbed strip without interfering with member 39, sothat within the area of operation of member 33 the pressure member 39will not engage with and act upon the reinforcing or ribbed strip.However, since pressure member 39 acts upon this portion of the strip infront of and behind member 33, and member 39 is preferably reciprocatedupwardly and downwardly at such speed that it hits upon the insole onceat every feeding movement of the strip of, for example, 1.8 mm., aperfect connection will be attained also at the inner side of the rib.
